I can't answer why it would be better than the S1R. Apparently there is a difference in the way the image is processed, one less layer of glass on the sensor, and micro lenses that help when using M glass on the SL2. I've run into some (very few) situations, where I can't grab focus in low light with my a7r iv, but I think part of that is because the PDAF isn't as good as an all contrast AF when trying to lock on to horizontal contrasting areas.
I had the Q2 for a short time and I didn't have a problem with focus. I did not, however, use tracking AF with the Q2. I do not expect the SL2 to perform as well as the a7r iv with respect to AF-C and, more specifically, Eye-AF.
I do have one on order with the 50 APO Summicron-SL. I still have my a7r iv, Sigma 35 1.2, 50 1.4 ZA and 85GM. I've put all my other lenses up for sale (not because I am set on moving away from the a7r iv, but rather because I use these three lenses more than any other). In the Sigma 35 thread I extended an invitation to anyone who wanted to try the SL2/50 Cron next to the a7r iv/50 1.4 ZA. I'm in NJ. Just bring a couple of SD cards and we can put both cameras through their paces. I'm very curious to see how the 50s will perform on their respective systems.
Thanks for the invitation but, the Leica system is of least interest to me. If I am to spend that level of money, I would do it on a MF system (the Fuji system seems very appealing). While, I care about image quality, I personally think Leica, Sony, Panasonic and Nikon (and even Canon to a degree) all offer worthy options (cameras and lenses) that are very close in IQ for all practical matters. This is particularly true for 50mm prime options across all these systems. I generally don't believe in non-quantified claims (magical renderings, 3D/4D pop, etc.) where the claimant doesn't even offer a side by side comparison. I went back and forth through the planar 50mm and sonar 55mm. While I like the planar a lot, I ended up selling mine and return to the 55mm even though the 50mm focal length is much preferable for me. build quality, click-less option are all great but the difference in weight was too much to justify for the difference in IQ. I have to say of all the great photos I see online, I see not that much of gear relevance. There are many amazing photos out there taken with mere medium or low quality gear far less expensive than my current gear let alone the super expensive Leica; and for me before all, I want to improve my photographic skills so someday, I will be proud of my achievement in the field regardless of the gear I used to take them.
I will be still looking forward to seeing great pictures taken with the Leica system and lenses (by you or others).
